Christmas party season can throw up all kinds of dress codes. One night might call for a proper suit, while the next is more about a good jumper, smart trousers and a jacket you can throw on without thinking too much about it.
The easiest way to get it right is to think about the level of formality first, then build your outfit from there. Tailoring covers the dressier end, shirts and knitwear work well for smart-casual plans, and trousers, shackets and jackets can be dressed up or down depending on what you wear with them.
These are the key categories to know this Christmas party season.
Men’s Christmas party suits & tailoring
If you’ve got a formal office party, Christmas awards night, dinner somewhere fancy or a big New Year’s Eve event in the diary, a great suit is the easiest way to look the part. And that doesn’t always mean going full black tie either! Colour, checks and double-breasted shapes can add a point of difference, while the right shirt, knitwear or accessories can shift the look up or down depending on the dress code and your personal style.
Four tailored looks to love:

Tailored Fit Blazer & Suit Trousers in Burgundy
- Our burgundy tailored suit is a strong choice if you want something a little different from black or navy. The colour gives it a festive feel, and you can dress it up with a shirt or down with a simple black knit underneath.
Tuxedo Blazer & Satin Seam Trousers in Black
- For more formal plans, our black tuxedo blazer with satin lapels and matching trousers has a much sharper evening feel. This is the suit to choose for black-tie events and New Year’s Eve parties if you have something extra special planned.

Cotton Rich Blazer & Suit Trousers in Grey Check
- For something more understated, why not choose our tailored fit grey check suit? With enough pattern to keep it interesting, this is both modern and easy to wear. Ditch the jacket to take things down a notch or add a tie and formal shoes when the occasion calls for more.
Double Breasted Blazer & Suit Trousers in Navy
- If you prefer something classic, our navy double-breasted suit gives you a polished option that makes an instant impression. The six-button double-breasted shape does most of the work for you, just add is a shirt, tie and your favourite smart shoes.
Men’s Christmas party jackets & coats
The right jacket or coat can make or break your Christmas party outfit, especially if you’re heading somewhere where you want to make a great first impression. For formal plans, it’s best to stick to clean shapes and smart fabrics, but for more relaxed nights out, why not go for something with a bit more attitude like faux leather fabric or a trending shape?
Four outer layers on our radar:

The Classic Faux Wool Trench Coat in Charcoal Grey
- Our classic faux wool trench coat in charcoal is the go-to choice for smart events. Throw it on over a suit for a work Christmas party, or wear it with tailored trousers and knitwear when you want to make an entrance.
Faux Wool Double Breasted Short Trench Coat in Chocolate
- Our chocolate brown double-breasted short trench coat is a more contemporary option that still looks classy. The warm chocolate tone works especially well through winter and feels just as at home over knitwear as it does over a smart shirt.

Faux Leather Collared Jacket in Black
- For nights out, our black faux leather collared jacket gives your outfit a bit more edge. Pair it with black trousers or dark denim and head out to the bar, club or a Christmas party with friends.
Padded Bomber Jacket in Black
- If your plans are really laid-back, our black padded bomber jacket is an easy one to reach for. Keep the rest of your outfit simple (like a jumper and jeans) and you’re good to go.
Men’s Christmas party knitwear
Not every Christmas party needs a shirt and blazer… especially if you just want to be warm and cosy! Our knitted jumpers and cardigans are a great option for family gatherings, festive lunches and casual drinks, and they can easily hold their own at a work do too if you choose a clean shape and pair it with smart trousers and shoes. Knitwear is all about how you style it.
Four knits for party season:

Knitted Roll Neck Jumper in Black
- Our black knitted roll neck jumper is one of the easiest pieces to dress up. Wear it under a blazer instead of a shirt, or pair it with tailored trousers for a simple evening look that can easily turn heads.
Cable Knit Crew Neck Jumper in Black
- Our black cable knit crew neck jumper has a more casual feel and is a great way to bring some texture into your outfit. Choose this knit for family get-togethers, pub plans or a Christmas dinner that doesn’t call for full tailoring.

Knitted Cardigan in Charcoal Grey Marl
- Our charcoal grey marl cardigan is ideal if you like to layer. Wear it over a T-shirt or shirt and keep the rest of the outfit simple for an easy, relaxed look that works perfectly for casual lunches and plans with family.
Faux Wool Quarter Zip Polo Jumper in Taupe
- Lastly, our taupe faux wool quarter-zip polo bridges the gap between smart and casual. The collar gives it a neater finish than a standard jumper, and it works particularly well with chinos or tailored trousers.
Men’s Christmas party shirts & shackets
One of the oldest tricks in the book when dressing up is to wear a shirt. It’s no wonder they’re a staple for office parties and fancy dinners! But a shirt doesn’t have to be really formal. Corduroy and heavier overshirt styles feel more suited to pub nights and anything with a looser dress code, and shackets give you a more relaxed way to layer for casual plans.
Four shirts and shackets to reach for:
The Classic Cotton Oxford Shirt in White
- You can’t go wrong with our classic cotton Oxford shirt in white. This versatile wardrobe staple can be dressed up or down depending on your plans. Wear it with a full suit and tie for a formal event or pair it with chinos when you want to keep things cleans and simple.
Corduroy Shirt in Dark Blue
- Our dark blue corduroy shirt brings texture and feels instantly more relaxed than a classic shirt. Button it up with smart trousers for a dinner date or wear it open over a T-shirt for drinks with friends.

Faux Wool Button Up Shacket in Charcoal Grey
- Another great option when you want to add a little structure is our charcoal faux wool button-up shacket. This stylish piece can be worn in place of a jacket and works especially well with simple layers underneath.
Cargo Pocket Shacket in Black
- Last but not least is our black cargo pocket shacket. This layer adds a little edge, especially when worn with dark denim and trainers. Choose this option for a night out with mates, or a pub Christmas lunch. You can’t go wrong!
Men’s Christmas party trousers
No Christmas party look is complete without trousers and let’s face it, the trousers you choose can completely change how dressed up the rest of your outfit feels. Tailored styles are the natural choice when you want to look smart without wearing a full suit, chinos cover the middle ground, and comfortable jeans are the staple to reach for every other type of plan.
Four trousers for the festive season:

Straight Leg Tailored Trousers in Brown Check
- Our brown check straight-leg tailored trousers are the perfect choice when you want something smarter than chinos but not as fancy as a full suit. Pair them with tonal knitwear or a shirt and let the checks do the talking.
The Classic Slim Fit Chino Trousers in Black
- Another great smart-casual option is our classic slim-fit chinos in black. These classic trousers are a real all-rounder for party season and can be worn with almost anything you already own.

Straight Fit Drawcord Trousers in Charcoal
- Our charcoal straight-fit drawcord trousers give you a more relaxed silhouette without looking too casual. Wear them with a polo knit, roll neck or simple shirt for an easy smart-casual outfit that just works.
Straight Leg Jeans in Rinse Wash
- For more casual plans, we always vote denim. Our rinse-wash straight-leg jeans have a darker wash keeps them looking neat, and a classic straight-leg fit that works for every body type. You can even dress them up with a smart knit and a stylish jacket.
What to wear to a Christmas party
The most important thing to remember when it comes to Christmas party dressing is that you can meet almost any dress code if you have a few key pieces to build your look around.
Tailoring takes care of the formal plans, while knitwear and shirts give you plenty of options when you need something more relaxed. Add a good pair of trousers and the right outer layer and you can easily shift your look depending on where the night takes you.
